- Another way of visualizing the genetic intelligence of an organism, say
- human.
-
- With the exceptions mentioned earlier in this thread, each of the 10^14
- cells in the human body has the same DNA content. From a functional point
- of view, we can think of a single set of DNA memory controlling 10^14
- parallel processors.
-
- Each of these processors has it's own set of I/O channels representing the
- information exchange across a single nuclear membrane, hormones coming in,
- mRNA going out (as well as other molecules I don't know about).
-
- The intelligence lies between the nuclear input and the nuclear output and
- is under genetic control. It may be that the computing power per cell can
- be thought of as being somewhat less than 3 x 10^5 instructions per second,
- once we allow for redundancy. In total however, the 10^14 parallel
- processors represent a heck of a lot of data processing.
-
- The next argument coming down the pike will be the redundancy of identical
- cells in a given type of tissue.
-
- I'll counter in advance. Even if all cells in the body were identical,
- each is under individual control, resolution counts for something. 10^14
- pixels would make a pretty high resolution computer monitor, and it would
- take quite a computer to generate a animated picture with that much
- resolution.
